Charge anywhere without opening a data connection
A USB cable is not just a power lead. The same plug carries data, which is the whole point of USB, and it means any socket you charge from is also a potential data connection. Airport charging kiosks, hotel bedside ports, hire cars, conference tables. You have no idea what sits behind any of them, and a compromised port can attempt to read from or write to a connected phone.
The data blocker solves the problem physically. It is a small adaptor that sits between your cable and the socket, and inside it the data pins are simply not connected. There is no setting to get wrong and no software involved. Power flows, data cannot, because the wires for it are not there.
Made by the original, chosen by us
We supply PortaPow blockers, the original maker, building them in the UK since 2009, with their blockers used by government agencies in the US, UK, Canada and New Zealand. The transparent construction lets you see for yourself that the data lines are absent, which is exactly the sort of verify-it-yourself design we like. At $25 it is the cheapest piece of security you will ever buy, and one for the travel bag of every phone owner, crypto or not.
